Six Gram-negative, rod-shaped, non-spore-forming bacterial strains were isolated from small holes on plaster walls of the stone chamber interior of the Kitora Tumulus in Asuka village, Nara Prefecture, Japan. These were investigated by means of a polyphasic approach. All the isolates were strictly aerobic and motile by peritrichous flagella. Phylogenetic trees generated based on 16S rRNA gene sequences identified two novel lineages (comprising five isolates and one isolate, respectively) within the genus Gluconacetobacter . The isolates were characterized by having Q-10 as the major ubiquinone system and C18 : 1ω7c (58.7–63.1 % of the total) as the predominant fatty acid. DNA–DNA hybridization experiments endorsed the species rank for the two lineages, for which the names Gluconacetobacter tumulicola sp. nov. (type strain K5929-2-1bT = JCM 17774T = NCIMB 14760T) and Gluconacetobacter asukensis sp. nov. (type strain K8617-1-1bT = JCM 17772T = NCIMB 14759T) are proposed.

Two sporulating bacterial strains designated CECAP06T and CECAP16 were isolated from the rhizosphere of the legume Cicer arietinum in Argentina. Almost-complete 16S rRNA gene sequences identified the isolates as a Paenibacillus species. It was most closely related to Paenibacillus cineris LMG 18439T (99·6 % sequence similarity), Paenibacillus favisporus LMG 20987T (99·4 % sequence similarity) and Paenibacillus azoreducens DSM 13822T (97·7 % sequence similarity). The cells of this novel species were motile, sporulating, rod-shaped, Gram-positive and strictly aerobic. The predominant fatty acids were anteiso-C15 : 0, C16 : 0 and iso-C16 : 0. The DNA G+C content of strains CECAP06T and CECAP16 was 51·3 and 50·9 mol%, respectively. Growth was observed from many carbohydrates, but gas production was not observed from glucose. Catalase and oxidase activities were present. The isolates produced β-galactosidase and hydrolysed aesculin. Gelatinase, caseinase and urease were not produced. The results of DNA–DNA hybridization showed that the strains from this study constitute a novel species of the genus Paenibacillus, for which the name Paenibacillus rhizosphaerae sp. nov. is proposed. The type strain is CECAP06T (=LMG 21955T=CECT 5831T).

A Gram-negative, non-motile, non-spore-forming and rod-shaped bacterial strain, CH15-1T, was isolated from a sediment sample taken from Daechung Reservoir, South Korea, during the late-blooming period of cyanobacteria. Strain CH15-1T grew optimally at pH 7.0 and 30 °C. A phylogenetic analysis based on 16S rRNA gene sequences confirmed that strain CH15-1T belongs to the genus Arenimonas with the similarity range from 92.6–97.4 % and is closely related to Arenimonas oryziterrae YC6267T (97.4 %), Arenimonas composti TR7-09T (95.4 %), Arenimonas metalli CF5-1T (94.7 %), Arenimonas malthae CC-JY-1T (94.6 %) and Arenimonas donghaensis HO3-R19T (92.6 %). However, the DNA–DNA hybridization between strain CH15-1T and the closest strain, Arenimonas oryziterrae YC6267T, was 8.9–12.9 %. The DNA G+C content was 63.9 mol% compared to A. oryziterrae YC626T, 65.8 mol%. Strain CH15-1T included Q-8 as the major ubiquinone and phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and phosphatidylmonomethylethanolamine as the major polar lipids. The major fatty acids (>5 %) were iso-C15 : 0, iso-C16 : 0, iso-C14 : 0, iso-C11 : 0 3-OH, iso-C17 : 0 and summed feature 9 (iso-C17 : 1ω9c and/or C16 : 0 10-methyl). On the basis of phylogenetic, phenotypic and genetic data, strain CH15-1T was classified in the genus Arenimonas as a member of a novel species, for which the name Arenimonas daechungensis sp. nov. is proposed. The type strain is CH15-1T ( = KCTC 23553T = DSM 24763T).

A novel facultatively methylotrophic, Gram-negative, rod-shaped bacterium, designated strain S2R03-9T, was isolated from jeotgal, a traditional Korean fermented seafood. The organism was strictly aerobic, motile by means of a single polar flagellum, non-sporulating and catalase- and oxidase-positive. Strain S2R03-9T grew in the presence of 0–1 % (w/v) NaCl and at pH 6.0–10.0, with optimum growth in the absence of NaCl and at pH 7.0. It grew at temperatures in the range 20.0–30.0 °C, with optimum growth at 30 °C. Colonies grown on R2A medium were non-pigmented, opaque and creamy white. Phylogenetic analysis based on 16S rRNA gene sequences indicated that it was most closely related to Methylobacterium organophilum JCM 2833T (96.6 % similarity) and the phylogenetic similarities to all other Methylobacterium species with validly published names were less than 95.0 %. The DNA G+C content was 64.9 mol%. The phylogenetic analysis, the phenotypic assessment and the chemotaxonomic data (major ubiquinone, Q-10; major fatty acids, C18 : 1 and C18 : 0) showed that S2R03-9T represents a novel species within the genus Methylobacterium in the class Alphaproteobacteria, for which the name Methylobacterium jeotgali sp. nov. is proposed. The type strain is S2R03-9T (=KCTC 12671T=LMG 23639T).

Four Gram-negative, motile, rod-shaped bacterial strains were isolated from soil samples collected from south-east China. A taxonomic study including phylogenetic analysis based on 16S rRNA gene sequences and phenotypic characteristics was performed. DNA G+C contents of the four strains were 63–66 mol%. Their predominant ubiquinone was Q-8. The fatty acid profiles contained C16 : 1 ω7c (36·9–54·7 %) and C16 : 0 (22·8–25·5 %) as the major components. Based on their phenotypic characteristics, phylogenetic position as determined by 16S rRNA gene sequence analysis and DNA–DNA hybridization results, the four isolates are considered to represent four novel species of the genus Massilia, for which the names Massilia dura sp. nov. (type strain 16T=CCTCC AB 204070T=KCTC 12342T), Massilia albidiflava sp. nov. (type strain 45T=CCTCC AB 204071T=KCTC 12343T), Massilia plicata sp. nov. (type strain 76T=CCTCC AB 204072T=KCTC 12344T) and Massilia lutea sp. nov. (type strain 101T=CCTCC AB 204073T=KCTC 12345T) are proposed.

Strain HMF4947T, isolated from the bark of a ginkgo tree, was a pale-pink coloured, Gram-stain-negative, non-motile, strictly aerobic and rod-shaped bacterium. The isolate grew optimally on Reasoner's 2A agar at 30 °C, pH 7.0 and with 0 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain HMF4947T belonged to the genus Hymenobacter and was most closely related to Hymenobacter metalli A2-91T (96.9 % sequence similarity) and Hymenobacter pomorum 9-2-1-1T (96.5 %). The average nucleotide identity and estimated DNA–DNA hybridization values between strain HMF4947T and Hymenobacter arizonensis DSM 17870T were 74.3 and 20.5 %, respectively. The major fatty acids were summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c), iso-C15 : 0 and C16 : 1  ω5c. The predominant isoprenoid quinone was menaquinone-7. The polar lipids comprised phosphatidylethanolamine, one unidentified aminoglycolipid, three unidentified aminophospholipids, one unidentified phospholipid, three unidentified aminolipids, two unidentified glycolipids and three unidentified polar lipids. The genomic DNA G+C content was 59.3 mol%. Thus, based on phylogenetic, phenotypic and chemotaxonomic data, strain HMF4947T represents a novel species of the genus Hymenobacter , for which the name Hymenobacter ginkgonis sp. nov. is proposed. The type strain of the species is strain HMF4947T (=KCTC 72780T=NBRC 114271T).

Clostridium diolis shares high similarity based on 16S rRNA gene sequences and fatty acid composition with Clostridium beijerinckii . In this study, the taxonomic status of C. diolis was clarified using genomic and phenotypic approaches. High similarity was detected among C. diolis DSM 15410T, C. beijerinckii DSM 791T and NCTC 13035T, showing average nucleotide identity on blast and in silico DNA–DNA hybridization values over 97 and 85 %, respectively. Results of investigations for substrate utilization and enzyme activity displayed no striking differences between C. diolis DSM 15410T and C. beijerinckii JCM 1390T. Based on the results, we propose the reclassification of Clostridium diolis as a later heterotypic synonym of Clostridium beijerinckii . The type strain is ATCC 25752T (=CIP 104308T=DSM 791T=JCM 1390T=LMG 5716T=NCTC 13035T).

A non-motile, rod-shaped, light-yellow-pigmented bacterium, designated strain WPCB159T, was isolated from freshwater samples collected from the Woopo wetland in Korea. The cells were Gram-negative, aerobic and catalase- and oxidase-positive. The major fatty acids were C16 : 1 ω7c (34.8 %), iso-C15 : 0 (24.2 %) and C16 : 0 (9.4 %). The DNA G+C content was 44 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain WPCB159T forms a lineage within the genus Dyadobacter (family ‘Flexibacteraceae’) and is closely related to Dyadobacter hamtensis HHS 11T (97.8 % sequence similarity) and to other members of the genus Dyadobacter (95.2–96.8 % sequence similarity). The phenotypic characteristics and DNA–DNA hybridization relatedness data indicate that strain WPCB159T should be distinguished from D. hamtensis HHS 11T. On the basis of the evidence presented in this study, strain WPCB159T represents a novel species of the genus Dyadobacter, for which the name Dyadobacter koreensis sp. nov. is proposed. The type strain is WPCB159T (=KCTC 12537T=NBRC 101116T).

Two non-motile, Gram-staining-negative, yellow-pigmented bacterial strains designated HMD1001T and HMD1033T were isolated from the water of a mesotrophic artificial lake in Korea. A phylogenetic tree based on 16S rRNA gene sequences indicated that both strains could be assigned to the genus Flavobacterium ; strain HMD1001T appeared most closely related to Flavobacterium fluvii H7T (96.8 % sequence similarity), F. succinicans DSM 4002T (96.6 %) and F. hydatis DSM 2063T (96.6 %) whereas strain HMD1033T appeared most closely related to Flavobacterium psychrolimnae LMG 2201T (96.2 %), F. segetis AT1048T (96.2 %) and F. weaverense AT1042T (96.2 %). The major fatty acids of strain HMD1001T were iso-C15 : 0 (21.5 %), summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c; 18.0 %) and iso-C15 : 1 G (7.6 %), whereas those of HMD1033T were summed feature 3 (23.8 %), iso-C15 : 0 3-OH (16.9 %), iso-C15 : 0 (15.3 %) and anteiso-C15 : 0 (12.1 %). The genomic DNA G+C contents of strains HMD1001T and HMD1033T were 35.9 and 32.2 mol%, respectively. Phylogenetic and phenotypic evidence indicates that strains HMD1001T and HMD1033T represent two novel species of the genus Flavobacterium , for which the names Flavobacterium yonginense sp. nov. (type strain HMD1001T  = KCTC 22796T  = CECT 7594T) and Flavobacterium myungsuense sp. nov. (type strain HMD1033T  = KCTC 22825T  = CECT 7649T) are proposed.

Two bacterial strains, designated JAM1T and JAM7T, were isolated from a methanol-fed denitrification system treating seawater at the Montreal Biodome, Canada. They were affiliated within the genus Methylophaga of the Gammaproteobacteria by analysis of the 16S rRNA gene sequences. Strain JAM1T had the capacity to grow under denitrifying conditions by reducing nitrate into nitrite which is unique among the species of the genus Methylophaga . Major fatty acids were C16 : 1ω7c or ω6c, C16 : 0 and C18 : 1ω7c or ω6c. The major ubiquinone was Q8. Both strains required vitamin B12 and Na+ ions for growth. The genomes of strains JAM1T and JAM7T have been completely sequenced and showed a DNA G+C content of 44.7 mol% and 47.8 mol%, respectively. Growth occurred at pH 6–11 and at 0.5–8 % NaCl. Both genomes contained predicted ORFs encoding the key enzymes of the ribulose monophosphate pathway. Also, operons encoding two nitrate reductases (Nar), two nitric oxide reductases (Nor), one nitrous oxide reductase (Nos) and one truncated nitrite reductase (NirK) were clustered in a 67 kb chromosomal region in strain JAM1T. No such operons were found in strain JAM7T. These results supported the affiliation of the two strains as novel species within the genus Methylophaga . The names Methylophaga nitratireducenticrescens sp. nov. for type strain JAM1T ( = DSM 25689T = ATCC BAA-2433T) and Methylophaga frappieri sp. nov. for type strain JAM7T ( = DSM 25690T = ATCC BAA-2434T) are proposed.
